simple_system - System Information for Eiffel

Overview

simple_system provides SCOOP-compatible system information access for Eiffel applications. It wraps Win32 system APIs through a clean C interface, enabling queries about the computer, processor, memory, and operating system without threading complications.

Part of the simple_* ecosystem of focused, single-purpose Eiffel libraries.

Quick Start

Installation

<library name="simple_system" location="$SIMPLE_EIFFEL/simple_system/simple_system.ecf"/>

Basic Usage

local
    sys: SIMPLE_SYSTEM
do
    create sys

    -- Computer info
    print ("Computer: " + sys.computer_name + "%N")
    print ("User: " + sys.user_name + "%N")

    -- Directories
    print ("Windows: " + sys.windows_directory + "%N")
    print ("Temp: " + sys.temp_directory + "%N")

    -- Processor info
    print ("CPUs: " + sys.processor_count.out + "%N")
    print ("Architecture: " + sys.processor_architecture + "%N")
    print ("64-bit: " + sys.is_64_bit.out + "%N")

    -- Memory info
    print ("Total RAM: " + sys.total_memory_gb.out + " GB%N")
    print ("Available: " + sys.available_memory_gb.out + " GB%N")

    -- OS info
    print ("OS Version: " + sys.os_version_string + "%N")
    print ("Windows 11: " + sys.is_windows_11.out + "%N")
end
